This is such a silly argument. A movable awning isn't some complex apparatus, it's literally a hinge and two sticks. You're trying to frame this as some kind of an expensive problem when it really isn't.
Connected to a gear that needs oil, a chain that needs oil and can rust, or a rope that withers. Being overly dismissive of failure modes isn’t a good look. I don’t claim that fixed awnings are God’s gift to humanity, just that they don’t have some of the drawbacks associated with moving parts. The amount of emotional reaction I’ve received to that completely factual statement is frankly ridiculous.
You're overlooking the fact that these are incredibly common in the Netherlands, yet the massive problems you describe are nowhere to be found. Most people get away with giving them some love maybe every few years when they get creaky, if even that. Your argument is about as reasonable as saying we shouldn't have door hinges or door locks because moving parts have drawbacks. It's silly, these systems are so simple that they require next to no upkeep for years at a time.
Indeed we shouldn’t have hinges or locks because moving parts have drawbacks, in contexts where that matters. For instance portals that don’t need a door at all, or walls that don’t need to open. Would you argue that every open passageway should have a door blocking it, and every wall should have hinges installed? No, that’s ridiculous. It’s equally ridiculous to get this angry about the simple fact that fixed awnings have upsides, and depending on the context they might be a better choice than retractable ones.
